Heretic of The Seventh Circle
I have also run and played in games at those levels, and experienced no particular problems (or at least, no more than at other tiers, Bc CR is a crapshoot in 5e at literally every level).Check the CR 9-11 creatures. They all have well over 100 hp and can make 2-3 attacks. Mooks with several attacks and 100+ hp? A bookkeeping nightmare.
I’ve run a game at tier 4. It’s a mess. The saving throw issue is real, and it’s awful to have a player taken out for several rounds by a stun or incapacitate because they have a 0-10% chance of success. Massive hp pools everywhere, just bags of hp since that becomes the main defense as opposed to AC.
I can do epic boons, or not advancing numbers. But then how is that different from what we already have?
You might note, before I continue, that I already said earlier that I voted “no”.
However, I do support a 10-level Epic Destiny set of features that can be chosen when “epic” is turned on, whether that is at level 1, 11, 3, 17, or 20, and that can also be spread out to every other level starting at level 1. An ED would be features similar to boons and such, but organized to fit an epic theme and concept without a DM having to figure out each ability by hand every time.
Post 20, it wouldn’t increase basic numbers, because then you have to adjust many many monsters CR and texts.
